3GPP transmitter measurements with R&S®
Key Facts
  • The application firmware adds measurement functions in line with the 3GPP specifications for the FDD mode to the Rohde & Schwarz signal and spectrum analyzers.
  • R&S®FS-K73
    • The R&S®FS-K73 application firmware provides the functionality needed for user equipment testing
  • R&S®FS-K73+
    • The R&S®FS-K73+ application firmware adds HSPA+ capabilities to the R&S®FS-K73.

Brief Description The R&S®FS-K73 application firmware can be installed on all models of the R&S®FSQ, R&S®FSU, R&S®FSG, R&S®FSUP, R&S®FSMR, R&S®FMU and R&S®FSP signal and spectrum analyzers, enhancing the range of applications to include code domain power and modulation measurements on 3GPP FDD signals. HSDPA and HSUPA signals in the uplink for user equipment are covered by R&S®FS-K73. R&S®FS-K73+ adds the capabilities to measure HSPA+ signals in the uplink. The 4PAM modulation format is automatically detected and the residual code domain error calculated in line with the standard.
